Knights chief executive Matt Gidley indicated the club would now weigh up possible action against Mason over the incident.

“With the court process now complete, the club will continue to review the matter internally,” Gidley said.

“Our role as a club is to consider all information before handling the matter in accordance with our code of conduct. The club takes this matter very seriously and will continue to educate our players in acting responsibly.”

The incident was part of a troubled off-season for the Knights which included the incarceration of recruit Russell Packer for assault.

The Knights lost their opening game of the season 30-8 to Penrith on Saturday, with fullback Darius Boyd (hamstring), captain Kurt Gidley (concussion) and playmaker Tyrone Roberts (concussion) all failing to finish the match.
